Review of Sword Art Online

I'm gonna write this review in 2 sides, the 1st half of the anime and the 2nd half. The 1st episode was meh and I found it like a stupid idea but when I continued watching the show it started to get me watching and even I got a little addicted like I wanted to see more. The other side when (SPOILER) everyone got out except Asuna was bad. (OVER with the spoiler) It started getting boring and started getting annoying cliches like oversexualizing Asuna ,(SPOILER) the terrible felt crush by Kirito's cousin to Kirito (OVER with the spoiler) and terrible villan. And the ending was toopredictable.
As the art and sound of the anime is pretty ok.
The characters are ok except of Kirito. I don't know how to say it but Kirito felt like a boring hero in the 2nd part.
Overall 1st side of the anime: 9/10 2nd side of the anime:4/10
